According to the results of the study, the best compression and bending strength indicators are typical for cement-building mixtures containing 5% ferrite of steelmaking slag. Energy-dispersion analysis of the elemental composition( EDA), separation by chemical analysis allowed us to study the structure of ferrite waste, to determine the oxides of iron, silicon, manganese, combined with lime or dolomite, which affect the favorable mode of obtaining the optimal formulation of the repair mixture. Research has shown that metallurgical waste is a valuable raw material for cement and concrete. The use of steelmaking slag instead of expensive cement will allow creating waste-free production complexes based on a deep study of the properties of secondary raw materials and their standardization, development of new technologies, and contributes to solving environmental problems of production.
